SPRIN'G BOOT.

Application filed August 7, i924. Serial' No. 730,562.

To all wwm t may concern:

Be it known thatI, JOSEPH C. Srocn,

a citizen ofthe United States, residing at N ew York city, in the county of New York 5 and State of New York, have invented certain new and useful Improvements in Spring Boots, of which the following is a specification.

This invention relates in general to covers for laminated springs, and particularly to the type of coverslas used in connection with laminated automobile springs.

l am aware that it has been proposed to enclose thevehicle springs with flexible covering having for its object to protect the springfand the lubricant contained therein. The various methods used have attempted to cause the cover to fit snugly to the spring, at the same time prevent the lubricant from running out and to provide means for introducing the lubricant into the cover.

It has been found, however, in practice, that the covers do not always lit tightly and the edges which are laced or otherwise closed, do not meet, lthereby allowing lubricant to leak out.

.Vhen the cover is made up of afplurality of pieces, it has been found that if the stitching gives way, the boot opens and no longer retains its function of maintaining the grease around the spring.

One of the objects of the present invention is the formation of the sides to accommodate the greater diameter of Athe spring clips, otherwise the boot has to be stretched `into shape over the springs and is subjected to great strain. Without the stretchingof the material and leakage of grease.

formation of the sides as shown, there is Still another object of the invention is to provide a cover formed to t over the spring.

Another. object of my invention is to provide reinforcing means at the top of the spring boot where the greatest wear occurs.

A still further object is to provide construction of spring boot so made that if the forming stitches give way the boot will still be operative.

rlhe present invention has further adl5@ vantages in that it can be put on quickly and it is not necessary to soak the cover before attaching to the spring. This soaking and stretching is a tedious operation.

4The lubricant can be placed inside at the 65 top of the cover and, therefore, it is not always required to separately grease the springs before putting the boot on, thereby savingl time.

lith these and other objects 'in 'view l@ which may be incident to my improvements, the invention consists in the parts andcombinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention, may be "varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.`

In order to make my invention more clearly understood, l have shown in the accompanying drawings means for carrying the same' into practical ell'ect without liraiting the improvements in their useful applications to the particular constructions, a5.

which for thel purpose of explanation, have been made the subject of illustration.

In the drawings Figure l vis a perspective view showing a' cover partially laced to a spring;

Fig. 2 is a sectional view along the line 2 2 of Fig. l; Y Fig. 3 is a bottom view showing the boot in place on the narrow end of the spring;

Fig. 4C is a bottom plan view of the form 95 shown in Fig. 1, with the sides extended;

Fig. 5 is a sectional view along the line 5&5 of Fig. l.:-

form of springs clips Fig. 6 is a sectional view along the line 6-5 of Fig. 4;

' `Fig. 7 is a top plan view showing a modioation of the form shown in Fig. l; l ig. 8 is a top plan view showing an other modification of the form shown in yhereinafter described. v

When the boot l is placed over the spring A., the lobes 3 formed on the side members 2 accommodate the greater diameter l0 (Fig. 2) within the boot.

vside members 2 has an apron 1l fastened of the'spring clips b ande.

The bootl has a top 5 (Fig. 5) shaped.

by means of longitudinal ribs 6, the ribs being stitched at 7, as shown in Figs. 5 and 6. The ribs 6, besides serving as a shaping means for the top 5 of the boot l,

ive a' double thickness edge. The stitches may come out and the boot will still be operative, maintaining its position around the spring and preventing leakage of the lubricant.

At the extremities and on the inside of the boot are attached pieces of compact and iexible material 8, such as felt or other suitable material, the material forming a flap 9 .Which functions to retain the lubricant One of the to its outer edge 12. The apron acts as a retainer for the lubricant 10 and also serves to' reenf'orce the joint 13 when the boot is laced to the spring. At the time the boot isplaced in position around the spring, the apron or Hap ll is folded back upon itself, as shown in Fig. 5, which indicates the position of the apron l1 after the boot is fastened in place.

At the extremities of the boot on the outside are attached straps 1i. The straps are stitched to the side members 2 and the top 5, serving to reenforce and strengthen the ends of the boot. This construction positively prevents stretching of the dexible cover with consequent leakage of the grease.

'Thevside members 2 are provided with eyelets l5 for the lacing '16. The eyelets on the side member 2 to which the apron or flap ll is attached, serve as a fastening means to attach the apron l1 `to the side member.

A modification of the form in Fig. 1 is shown in Fig, 7, which shows.aa-1:boot or cover having one pair of lobes '3 'on the side members 2.l This form is used with a spring having only one spring cli Referring to Fig, 8, Whic shows another modiiicationofthe form shownl in Fig. 1,

incassa instead oi forming the side members 2 with lobes 3, the longitudinal ribs 6 are formed with bulges or humps 17 to give the formation which will accommodate the greater diameter of the spring clip.

Theboot or cover as described is easily and quickly applied to the. sprin Since it is already formed to fit the con gui-ation ofl thespring; it is not necessary to wet or soak the boot .in water before attaching it. This saves a great deal of time for a mechanic in attaching the cover to the springs of asingle car.

The grease can be applied to the cover before the cover is'placed around the spring and in many instances it is not necessary to apply grease to the `spring before putting the cover in place. A cover applied in the above manner not only saves tlme, but also conserves the lubricant. The reenforcing straps at theextremities prevent the vcover from stretching at points Where the greatest possibility of leakage of grease occurs.

While l have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of'illustration, as it is apparent that many changes and variations may 'be made therein, by those skilled in the art, Without departing from the spirit of the invention, or exceeding the scopeof the appended claims.
